Heat soak - vented hood options that are not "louvered"

SouthArk370Z · 11-10-2013, 09:29 PM

I've always heard that's it's a bad idea to run straight water in an Aluminum engine because of corrosion. Antifreeze has corrosion inhibitors. Or is that another of my out-dated facts?

I've heard that, in addition to seals inside the motor need some of the conditioners in coolant to stay in good condition. Water wetter and similar additives claim to have seal conditioners and corrosion inhibitors so you can run water only, but ill always run at least a little coolant just to be sure.

Alstann, you're right on the vents being the best way to get hot air out of the engine bay. If there were a vented hood on the market I liked from a functional/aesthetic standpoint I'd start with that. I'm just not a huge fan of the options we have on that front, so I'm going to try adding the fans to the CSF radiator I've got, lowering the fan temperature more and running less antifreeze. If that isn't enough to keep temps stable, then ill start cutting holes.

I'm right there with you on that one.

I don't know if I love any vented hood enough to warrant spending money getting one, and then even more painting it. The Seibon one is my "favorite," but still, I'm a clean and simple guy for cars at the moment. I wonder if there is any plastic shrouding near the windshield we can remove, to allow the trapped air to somewhat escape from the engine bay? I've never looked.

Corrosion does occur to some extent, such as mineral deposits and small amounts of rust on the aluminium. The solution is to run straight 100% distilled water, usually purchased from a grocery store. Of course, in cold climates, this is a very bad idea.

Not distilled. You only want distilled! Normal water, bottle, house etc all have minerals in it that will corrode stuff.

When I do 100% water plus water wetter it's really not 100%. I just drain the radiator till it stops dripping. The block, water pump etc will still have regular antifreeze in it so in the end you may have something like 90% water, 9% antifreeze and 1% water wetter.
